Grim Series – Solid Fuel High Pressure Steam Boilers

Grim Series solid fuel Scotch type steam boiler can burn granular fuels such as lignite coal, pomace, pellets, sunflower husk, hazelnut shell, etc. with high efficiency, and its use is facilitated by automatic loading. If requested, an economizer can be added to the flue gas outlet to take advantage of the heat of the smoke gases. The economizer to be mounted on the back of the boiler allows the condensate water entering the boiler to be heated and returned to the boiler. Thus, fuel savings are achieved.
